Answer:
(-5 , 0)
(-2, 0)
(0, 20)
Step-by-step explanation:
y = 2x² + 14x + 20
x intercepts occur when y = 0
0 = 2x² + 14x + 20
0 = (2x + 4)(x + 5)
x = -5
or
x = -2
y intercept occurs when x = 0
y = 2(0)² + 14(0) + 20
y = 20
Step-by-step explanation:
Volume of sphere = 4/3 * π * r³
Since 36π = 4/3 * π * r³, r³ = 27 and r = 3.
Answer:
Solution given:
let age of Jailah be x and grandfather's age be y
according to the question
x=¼y-5.....(1)
x=12...........(2)
Now substituting value of x in equation 1
12 =¼y-5
12+5=¼y
17=¼y
doing crisscrossed multiplication
17*4=y
y=68
<u>Jailah’s </u><u>grandfather</u><u> </u><u>i</u><u>s</u><u> </u><u>6</u><u>8</u><u> </u><u>y</u><u>e</u><u>a</u><u>r</u><u>s</u><u> </u><u>o</u><u>l</u><u>d</u><u>.</u>
